The aim of this study is to use local resources, namely raw earth and sawdust wood to be used in building materials, in order to contribute to solving the housing problem and to reduce the energy consumption, through the use of raw earth constructions. To achieve this objective, the mechanical, physical properties (Young’s modulus, maximum compression stress, and flexural strength) and thermal properties (thermal conductivity and heat capacity) of raw earth bricks physically stabilized with cement (5%) and incorporating sawdust wood (3%; 5% and 10%) were studied. The results show that the sawdust-raw earth has interesting behavior with a maximum compressive strength of about 4 MPa. In addition, the results show that sawdust reduces the mechanical properties of earthen blocks but increases their ductility. The incorporation of 10% of sawdust decreases the Young's modulus of raw earth of 30% comparing to 3% of sawdust. In addition, the results showed that the thermal conductivity decreased from 1.1 W m−1 K−1 for the 3% sawdust sample, to 0.8 W m−1 K−1 for the 5% sawdust sample, and 0.7 W m−1 K−1 for the 10% sawdust sample, indicating an improvement in thermal insulation. Therefore, the results of this study give additional critical feedback to assist in evaluating the potential applications of sawdust as an insulating material for unfired clay blocks.
